Exceptions to caring for the poor?

A person may be poor because of self-indulgence.

Whoever loves pleasure will suffer want;
    whoever loves wine and oil will not be rich. - Proverbs 21:17

Someone may make a decent income but waste it on drugs, alcohol, cigarettes, expensive convenience foods, costly recreation, or gambling (including lotteries).

A person may be poor due to laziness.

 A slack hand causes poverty,
    but the hand of the diligent makes rich. - Proverbs 10:4

 The lazy person does not plow in season;
    harvest comes, and there is nothing to be found. - Proverbs 20:4

 Fools fold their hands
    and consume their own flesh. - Ecclesiastes 4:5

Ultimately, the lazy man is poor by choice.

Every act of provision to a lazy person who is poor removes the incentive to be responsible for themselves and makes them more dependent on others. Paul commands the Thessalonian church to stop taking care of the lazy and reminds them of the rule he issued when present with them.

  For even when we were with you, we gave you this command: Anyone unwilling to work should not eat.- 2 Thessalonians 3:10

The point is not to let people starve - the point is that  people who are faced with starvation will be motivated to work and support themselves as God intended.

The appetite of workers works for them;
    their hunger urges them on. - Proverbs 16:26

Lazy and self-indulgent people do not need financial support - they need incentives to no longer be lazy and self-indulgent.

 Laziness brings on deep sleep;
    an idle person will suffer hunger. - Proverbs 19:15

  Do not be deceived; God is not mocked, for you reap whatever you sow. - Galatians 6:7

The question is not simply, "What shall we do for the poor?" but "Which poor?" The truly poor must be helped. - thoughtfully and carefully.
